Good brew day. Mash temp was all over the place (probably due to opening it up and stirring), started at 70, then ended at 63
Based on boiling 12.00 gallonsliters at 1.065 for 60 minutes, this will decrease your wort by 4.00 gallonsliters, bringing your after boil OG to 1.087. You wanted an OG of 1.077. It looks like it will be over.
